ATTAGHING DEVICE FOR NONSKID CHAINS.

Application filed June 24, 1920.

To all whom it may concern:

Be it known that 1, CHARLES Moss, a citizen of the United States, and a resident of the city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Attaching Devices for Nonskid Chains, of which the following is a specification.

This invention relates to improvements in attaching device for non-skid chains, and has for its primary object to provide a simple and inexpensive means for quickly applying or attaching emergency non-skid chains to motor vehicle wheels.

' Broadly considered it is the main object of my present improvement to provide a device for the above purpose which is of such'construction that all of the various parts remain operatively assembled when the non-skid chain is removed from the wheel, aswell as when such chain is in its applied position.

It is one of the detail objects of the invention to provide an attaching means which is constructed in two complementary parts permanently attached respectively to the opposite ends of the chain, said parts adapted to embrace a wheel spoke, and having interlocking portions at one of their ends, and clamping means on the other end of one of said parts, including a swivel bolt adapted to be'seated in a recess in the end of 'the other part, a non-removable nut threaded on said bolt, and a washer acted upon by said nut, the end of the last-named part of the device being curved or bent at opposite sides of the recess therein so as to prevent the disengagement of thebolt from said recess in the event that the nut should be accidentally loosened.

Itis a further general object of the invention to provide a non-skid chain attaching device which can be applied to, or're-v moved'from the wheel with ease and facility, and which is of relatively simple con- Serial No. 391,388.

of a wheel having the improved chain at- 'taching device applied thereto.

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 1, and,

Figure 4 is a fragmentary perspective view of the interlocking end portions of the attaching clamp.

Referring in detail to the drawings,].5 designates the rim portion of an automobile wheel which is suitably secured upon the wheel spokes 6, and in which the wheel tire 7 is adapted to be arranged and secured in any approved manner.

In the illustrated embodiment of my invention I have shown the emergency non- .skid device as consisting of alength of link chain 8. It is, however, to be clearly understood that the present embodiment, which relates solely to the attaching means for the device, is not to be limited to such a chain or other specific" form of the non-skid means, since, obviously, the chainmight be provided intermediate of its length with ground engaging tread members of any desired and approved form.

. As illustrated, the attaching device comprises two complementary clamping plates 9 and 10 respectively, which are adapted to be positioned upon opposite sides ofone of the wheel spokes 6 to snugly embrace the same. To the outer side of each of these curved plates at the approximate center thereof one end link of the chain 8 is attached, by means'of a looped strap or bracket element 11, which, at its ends, is riveted, welded or otherwise permanently fixed to the plate.

One end of the plate 9 is provided'with an outwardlyprojecting lug 25 extending radially with respect to the spoke 6. The lug 25 carries a diagonally projecting flange 12 having a slot 13 to receive the tongue 14 carried by the adjacent end. of the companion curved plate 10. It will be noted, particularly with reference to Figure 3, that the flange 12 is substantially at a tangent to the curved plates 9 and 10 or parallel with a tangent to these plates.- The tongue 14 is curved with its convex side awayv from the wheel spokes.

the plate 9 and engaging the outer wall of the slot 13. A rounded heel'26 is formed between the plate 10 and the tongue 14:, this heel having a bearing on the lu 25. The convex side of the tongue 14 providing a bearing on the oute'r Wall of the slot 13 of flange 12, and the heel 26 with its hearing upon the lug 25 avoids distortionof these parts and of the members 9 and 10, prevents rattling. of the device and enables the--tongue- .to be umoreeasily centered. and engaged with.; the;slot13;.- I

At its opposite end the plate 9 is provided withspaceid hinge knuckles 15, inwhich a pintle 16 is permanently fixed. A- clamp bolt 17 is loosely engaged-at one of its: ends upon the medial portion ofL-the pintle 16 for free: swinging movement; Upon the threaded portionotthe-boltal'i" a washer 18 is disposed, and a -I -1;ut 19,-"preferably of the Wing type, is permanently threaded upon said boltr The gremoi al of the nut from the bolt is prevented by swagingthe endof the bolt as -at 20, so as". to increase the diameter thereof. J

r The corresponding vend of the other spoke embracing plate 10 is formed-with an outward-1y projecting lateral flange 21, which is medially-slotted, asshownat 22, ;to re- .ceive the bolt=17 The flange-21' at opposite sides ,of-the slot 22therein is curved or bent inam. outward Cll TGGlilOH ELSdHdlOfll/Qd at 23, the'pu eoseof which willbe presently explainedi v v 1 Inthe application of the emergency skid devices to the wheel; said devices are arranged in any-desired number,- and in suitably spaced relation transversely across the wheeli'tire, andtheattaching'plates o'r memhere 9- and lO on the'endsofthe' chain are brought together atuopposit-e sides of one Theseplatesat one of their ends are: connected by the interlock-ing- {tongue and-slotted flange; The bolt 17 ion ithe -otherhend of'th'e plate 9 at the oppositeside-otwthe spoke is then swung inwardly into the slot 22 in the opposed and of- {theplate 10.- The nut 19 is now adjusted-upon the bolt17'to urge the washer 18 againstt'he flange 21 and thereby draw {the ends: of the ,twoi plates 9"a n'd 10 together ;and tightly clamp said plates upon the spoke. In order to prevent'the scratching brvmanring-of the'finislr on (the wheel spokes these-plates are 'vprefe'rablv' lined upon their :cushioning fmateri'ah: as indicated 'at 24. Whena'thet'wo parts of the attaching clamp have thus be'en securely connected around the wheelspok'e, it will *be' seen that "the 'non-vsk'idw'device cwi'llbe zproperly 'he'ld in :po'sitio'n' upon the" :tire', and all possibility of separation, it is necessary. so-thre d the nu 19 outwardly for a cQn'siderable distance upon the threaded bolt. When the emergency skid device-is removed. trom the vehicle wheel, it will be-seen.

that; all partsxoflthe attaching means-for said device remainiconnected, so that they cannotbecome. separated and lost, whe eby the device would be rendered inapplicable to the wheel. --l[t -wil1- thus; be iapparent'th I have devised anconstruction and arrange- .mentotithei' attaching means tor non-skid devices which is of Iconsiderable: practical utility. At] the 1 same timexit; will'be noted that the article is of very simple construc .tion, and, as; the two plates or members of the attaching means are-at all times-connect'edtfothe links of the chain for application to the spoke, such. applieationmay be made with ease and fac-ility,Cwithout---,re-

quiring the manipulation of snap hooks or other ararious devices'fo-r' the attachment of the non-skid chains to the clamp The several rparts o f the device: are, also strong and durable, and will, therefore,

' serviceably withstand" severe usage:

From the; foregoing desc ptionv considered in connection with the drawings, the COIlSiiIEHCf/IQII; manner of operation and .sev-

era'l' advantages of my improved device willbe clearly understood: I-have hereindisclosed what Itconsider to bea very practical and satisfactory embodiment zOf the invention, though it is to betunderstood that'i-n practice the devicemay also be embodied in variousother alternative constructions; Accordingly I reserve the privilege of adopting all such changes and modificationswit-hin the spirit and scopenof the invention'as claimed.

Iclaim: 7 An attaching device for non-skid chains comprising a clamp composed'lof two plates, .saidiplatesrbeing' curved' outwardly in opposite directions to complementally'fifit about a spoke of awheelythe outside faces of such 'curved plates having straps to receiye' the non-skid chain, one of said plateshaving at one end an oi twar'dly and radially 'projectinghig; said Tug having" a sletted iian e I projecting angularly therefrom" and lying at substantially a tangent to the plates but "being spaced from the plates; the corresponding end of the companionplate'havinga rounded heel engaging thefa'djacent f e a sai lug and being firt efprovided with a curved tongue adapted to fit slidably through the slot in said flange, the convex side of said curved tongue being away from the companion plate, radially projecting flanges at the opposite ends of said plates, a hinged bolt carried by one of these flanges, the opposing flange being slotted to receive the bolt, such opposing flange having its corners turned outwardly away from the flange carrying the bolt and a bolt engaging ele- 10 inent confined by said outwardly turned corner portions.

In testimony that I claim the foregoing as my invention, I have signed my name.
